Meta heads to trial in lawsuit alleging its platforms drive social media addiction in teens

Meta is scheduled to face trial on Tuesday in a lawsuit brought by 29 attorneys general that focuses on how the company’s social media platforms affect teens.

According to the report, the case centers on allegations that Meta’s services contribute to “social media addiction” behaviors among young users. The complaint is framed around the potential harm to teenagers, and it is now moving from pretrial proceedings into a courtroom trial.

The trial’s timing highlights how state-led efforts to regulate or challenge big social media companies are increasingly taking concrete steps through litigation, not only policy proposals or platform policy changes.

Meta, which operates Facebook, Instagram, and WhatsApp, has repeatedly faced scrutiny over youth safety and engagement design, but Tuesday’s setting matters because the dispute is being litigated under specific legal claims rather than handled purely through voluntary commitments. In the report, the focus is on the alleged addiction impact on teens rather than on advertising practices or content moderation in general.

For Meta, the stakes extend beyond the immediate outcome of the case. Trials of this type can lead to injunctions or other court-ordered remedies that could affect product features, default settings, or how the company designs engagement systems for younger users, depending on what a court finds and what remedies are sought.

The litigation also adds to a broader U.S. pattern in which state governments have used consumer protection and public health-style theories to push back on social platforms. In this environment, legal timelines can also become operational milestones for companies, forcing business teams to prepare for discovery, witness testimony, and arguments about internal systems and incentives.

Notably, the report does not specify in the information provided what arguments Meta intends to raise, what specific product mechanisms are central to the plaintiffs’ theory, or what remedies the attorneys general are seeking. It also does not list which attorneys general are participating, which courts are involved, or whether the parties have agreed to any narrow issues for trial.

What to watch next is whether the case establishes a clear factual record about how Meta’s systems are alleged to influence teenage behavior, and whether the company’s defenses focus on causation, product design choices, or legal standards for imposing liability. The trial itself, beginning Tuesday, will determine what evidence the states can put before a judge or jury and what remedies, if any, may follow.
